Multimedia Interactive Teaching System and Method

Abstract

The present disclosure relates to a multimedia interactive teaching system and method. The system comprises a teaching controller, a learning terminal, a recording device, a speech collection device and a storage device, wherein the recording device is used for acquiring a real-time image and action data; the speech collection device is used for collecting real-time in-class speech information; the teaching controller is used for sending the teaching information collected by the recording device and the speech collection device to the learning terminal; and the storage device is used for storing the teaching information collected by the recording device and the speech collection device, so that a user can review an in-class teaching process by means of on-demand play over network.

Description

TECHNICAL FIELD[0001]The present disclosure relates to the field of multimedia teaching and, in particular to a multimedia interactive teaching system and method.BACKGROUND[0002]Most of the traditional multimedia classrooms use modern teaching devices, such as projectors, video presentation stands, computers, electric screens, amplifiers, speakers and electric curtains, to achieve the purposes of teaching, academic exchanges and lectures, so that the existing multimedia teaching requirements can be basically met. However, there are some significant problems in the use of the traditional multimedia classrooms and projection classrooms, which mainly lie in the following aspects:[0003]Firstly, devices in the traditional multimedia classroom are comprised of a projector, a computer, an electronic whiteboard and a speaker, etc., with complicated lines making the devices often fail, thereby increasing an enormous cost for later maintenance;[0004]Secondly, in the traditional multimedia cla...

Benefits of technology

[0013]In view of the deficiencies of the existing schemes, the technical problem to be solved by the present disclosure is to provide a multimedia interactive teaching system and method, which mainly improve a wireless remote control apparatus and an operation method therefor, a high-speed photographic instrument mechanism and an operation method therefor, and use a speech recognition clustering technology to perform segmentation and clustering on the obtained teaching speech information to recognize the corresponding speaker and separately store these pieces of speech information, thereby solving some problems existing in the existing schemes, and reducing teaching costs, improving the teaching flexibility and interactivity and improving the teaching effectiveness by means of the wireless multimedia information interactive teaching method in the present disclosure.

Problems solved by technology

However, there are some significant problems in the use of the traditional multimedia classrooms and projection classrooms, which mainly lie in the following aspects:

Firstly, devices in the traditional multimedia classroom are comprised of a projector, a computer, an electronic whiteboard and a speaker, etc., with complicated lines making the devices often fail, thereby increasing an enormous cost for later maintenance;

Secondly, in the traditional multimedia classroom, numerous devices are installed near the classroom platform, while the platform is also the region where students often carry out activities, such that the probability of damages to the devices is very high, and personal injury is liable to be caused to active students.

Thirdly, in the traditional multimedia classroom, it is generally dominated by teacher's explanation, while students are passively accepting for most of the time and are unable to achieve interactive learning, especially physical and chemical situational teaching, which cannot replace the real participation process, such that the teacher can merely teach in accordance with the established lesson preparation plan, thereby having a poor flexibility in the class, making the teacher have less room to play, and thus reducing the teaching effectiveness.

The above-mentioned interactive teaching system also has such a problem: the interaction between teacher and students in the wireless network platform cannot reach a barrier-free degree, and the system cannot automatically recognize and record information about a speech interaction between the teacher and the students, and their own speech records in a class cannot be reviewed afterwards.

The existing teaching system firstly needs to be equipped with a teaching terminal specific to a person; secondly, if a student wants to speak through the learning terminal, it is also necessary to align with a microphone or start the microphone to perform speech communication, failing to communicate with the teacher carefree.

For example, CN 105306861 discloses a network teaching recording and broadcasting method, in which a method for separately storing three types of data streams is used; however, there is still such a problem in the aspect of speech storage: such a speech recording function is completely carried out in accordance with actual conditions without recognizing the identity of a speaker and without reconstructing the speech of the speaker, so that if the recording environment is noisy, the recorded information is also noisy and the scene can barely be reproduced effectively.

This does not provide a personalized service, for example, when a student only wants to hear what he or she said or what the teacher said but does not want to hear what other students said, they cannot make a selection during playback, however.

In addition, there is still a problem in the existing teaching platform: the teacher terminal is usually fixed, and a teacher needs to make communication on the set platform or arrangement place of the teacher terminal, thereby lacking deep interaction with the students.

This does not make it possible for the teacher to go to the students for more active interaction as traditional teaching.

The existing Bluetooth wireless remote control apparatus cannot realize flexible control of speech, which is mainly realized in a wireless control manner by integrating basic operation apparatuses such as a keyboard and a mouse, and the functions thereof still have room for improvement.
